Entrance fee to battlefield is $10 per adult to a maximum $20 per vehicle. Motorcycles $15. An adult is 16 years or older.
After 5 pm until 8 pm it is free
You can also buy an annual National Parks Pass an it works all over the country. We paid $80 for my husband and I. Pretty sure it is good for the entire vehicle.
It's $20 a car load or $35 for an annual pass that gets in your car load. Hope that helps! (There is a discount for senior citizens also)
We used our parks pass and got a discount.
